Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

There are other potential explanations for the newly mapped blobs. For example, they may be made of crust-like material left over from the mantle's creation 4 billion years ago. Or they may ...

Two such blobs exist: one beneath the Pacific domain and the other beneath the African domain, the Live Science reported. "The composition of mantle domains reflects not only surface processes but ...

Scientists have identified mysterious formations deep in Earth’s mantle, raising new questions about the planet’s interior. These strange shapes, often referred to as "blobs," or "sunken worlds," ...

Although such a 'plum-pudding' mantle — one consisting of blobs of one composition dispersed in a matrix of another — has been invoked previously, the data assembled over the past few years ...

Potential patches of Earth's ancient crust, sometimes called "sunken worlds," may have just been discovered deep within the mantle, thanks to a new way of mapping the inside of our planet. However, ...

New research suggests that the blobs buried deep in Earth's mantle may be a billion years old. | Credit: KATERYNA KON/SCIENCE PHOTO LIBRARY via Getty Images Continent-size islands deep inside ...
